Python, tensorflow 环境搭建

windows
1.打开Python官网，点download中的windows 打开WEB浏览器访问http://www.python.org/download/
2.下载exe后缀的可执行文件，根据自己系统选择32位还是64位
3. 安装时要记得勾上add python to Path 选项，意思是把Python的安装路径添加到系统环境变量的Path变量中
4.根据需求安装


环境变量配置
一般装完直接可以从cmd中访问

如果没有：
首先需要在系统中注册python环境变量：
假设python的安装路径为c:\python3.6，
则修改我的电脑->属性->高级->环境变量->系统变量中的PATH为:
PATH=PATH;c:\python36

安装tensorflow
pip install --upgrade --ignore-installed tensorflow
pip install --upgrade --ignore-installed tensorflow-gpu
python –m pip install --upgrade --ignore-installed tensorflow


linux
1. 安装依赖环境
# yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
2.下载Python3
官网
# wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz
3. 安装python3
# mkdir -p /usr/local/python3
# tar -zxvf Python-3.6.1.tgz
# cd Python-3.6.1
# ./configure --prefix=/usr/local/python3
# make
#make install
5.建立python3的软链
# ln -s /usr/local/python3/bin/python3 /usr/bin/python3
6.将/usr/local/python3/bin加入PATH
# vim ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
Fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin：/usr/local/python3/bin
export PATH
按ESC，输入:wq 回车退出。
# source ~/.bash_profile
安装pip
1、安装pip前需要前置安装setuptools
wget --no-check-certificate  
https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26
tar -zxvf setuptools-19.6.tar.gz
cd setuptools-19.6
python3 setup.py build
python3 setup.py install
2.安装pip
wget --no-check-certificate  https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb
tar -zxvf pip-8.0.2.tar.gz
cd pip-8.0.2
python3 setup.py build
python3 setup.py install
安装tensorflow

最新版本的二进制文件链接地址，可以通过TensorFlow官网获取
https://www.tensorflow.org/install/install_linux
2. Pip 安装
pip install tensorflow==2.0.0-alpha0 
ip install tensorflow
